Abstract
Synthetic phospholipid compounds and their method of preparation, which compounds are phosphatidylethanolamine polycarboxyl polyalkylene glycols and are prepared by the reaction of a phosphatidylethanolamine, a polycarboxylic acid, such as succinic or glutaryl anhydride, and a polyalkylene glycol, such as polyethylene glycol.
